The design for running all Crashpad unit tests on Chromium’s try- and
buildbots involves pulling all tests into a single monolithic
crashpad_tests executable. Many Crashpad tests base the name of their
child executables or modules on the name of the main test executable.
Since the main test executable will have a different name in the
in-Chromium build, knowledge of the test executable name (referred to as
“module” here) needs to be added to the tests themselves.
This introduces TestPaths::BuildArtifact(), which allows the module name
to be specified. For Crashpad’s standalone build, the module name is
verified against the main test executable’s name.
TestPaths::BuildArtifact() can also locate paths in the alternate 32-bit
output directory for 64-bit Windows tests, taking on the responsibility
for what the new (5e9ed4cb9f69) TestPaths::Output32BitDirectory(), now
obsolete, did.

Rather than having the 64-bit build assume that it lives in
out\{Debug,Release}_x64 and that it can find 32-bit build output in
out\{Debug,Release}, require the location of 32-bit build output to be
provided explicitly via the CRASHPAD_TEST_32_BIT_OUTPUT environment
variable. If this variable is not set, 64-bit tests that require 32-bit
test build output will dynamically disable themselves at runtime.
In order for this to work, a new DISABLED_TEST() macro is added to
support dynamically disabled tests. gtest does not have its own
first-class support for this
(https://groups.google.com/d/topic/googletestframework/Nwh3u7YFuN4,
https://github.com/google/googletest/issues/490) so this local solution
is used instead.
For tests via Crashpad’s own build\run_tests.py, which is how Crashpad’s
own buildbots and trybots invoke tests, CRASHPAD_TEST_32_BIT_OUTPUT is
set to a locaton compatible with the paths expected for the GYP-based
build. No test coverage is lost on Crashpad’s own buildbots and trybots.
For Crashpad tests in Chromium’s buildbots and trybots, this environment
variable will not be set, causing these tests to be dynamically
disabled.

This introduces the Annotation object, used to declare typed

The AnnotationList implements a lock-free linked list, into which
Annotation objects are added exactly once, when they are first set.
Clearing an Annotation merely marks it internally as such, rather than

This was discovered in a trunk Clang build, during which a

The warning is not produced by earlier Clang versions or by GCC because
the “delete” happens in a system header, <memory>, when performed by

[pid:tid:yyyymmdd,hhmmss.mmm:ERROR file_io.cc:89] ReadExactly: expected

These messages were being produced by crashpad_handler, in the
LoggingReadFileExactly() call in
ExceptionHandlerServer::ServiceClientConnection().
sizeof(ClientToServerMessage) is 36. crashpad_handler believed that a
client was connecting, but the client sent no data.
This was tracked down to the use of os.path.exists() in
end_to_end_test.py to wait for crashpad_handler’s named pipe to be
created. Checking named pipe existence in this way appeared to be a
client connecting to the the pipe server in crashpad_handler, although
of course no real client was connecting and no message was forthcoming.
I found that running “dir” on the named pipe’s path produced the same
result.
Using WaitNamedPipe() is an alternative that can be used to signal when
the named pipe’s path exists. Furthermore, it tests more than mere
creation, it indicates that the pipe server has become ready to service
clients. That’s not necessary in this case as proper clients already
need to deal with this on their own, but checking it in
end_to_end_test.py should be harmless.

In the 64-bit version of the structure, padding is needed between
ShowWindowFlags and WindowTitle.
The CurrentDirectores (yes, that’s how it’s spelled) members would have
been interpreted incorrectly because STRING was defined incorrectly. The
length fields are USHORT, not DWORD. In the 64-bit version of the
structure, a padding member ensured that the structure was at least the
correct size. In the 32-bit version of the structure, this caused the
structure size to be inflated, so all but the first CurrentDirectores
element and any struct member that followed would appear at incorrect
offsets, and the overall struct size being read was larger than
appropriate.
This resolves crashpad_handler logging (usually) three errors while

hanging_program.exe is used by crash_other_program.exe, which is in turn
used by end_to_end_test.py. It hangs by loading loader_lock_dll.dll,
which squats in its entry point function while the loader lock is held.
hanging_program.exe needs to do some work in its Thread1() before the
loader lock is taken (a SetThreadPriority() call), and needs to do some
work in its main thread once the loader lock is held (it needs to signal
crash_other_program.exe that it’s successfully wedged itself).
Previously, proper synchronization was not provided. A 1-second Sleep()
was used to wait for the loader lock to be taken. Thread1() pre-work was
only achieved before the loader lock was taken by sheer luck. Things
didn’t always work out so nicely.
This uses an event handle to provide synchronization. An environment
variable is used to pass the handle to loader_lock_dll.dll, because
there aren’t many better options available. This eliminates both flake
and the unnecessary 1-second delay in hanging_program.exe, and since
this program runs twice during end_to_end_test.py, it improves that
test’s runtime by 2 seconds.

This uses “static” at function scope to avoid making local copies, even
in cases where the compiler can’t see that the local copy is
unnecessary. “constexpr” adds additional safety in that it prevents
global state from being initialized from any runtime dependencies, which
would be undesirable.
At namespace scope, “constexpr” is also used where appropriate.
For the most part, this was a mechanical transformation for things
matching '(^| )const [^=]*\['.
Similar transformations could be applied to non-arrays in some cases,
but there’s limited practical impact in most non-array cases relative to
arrays, there are far more use sites, and much more manual intervention

In 10.13, modules loaded from the dyld shared cache appear with __TEXT
segments that have a nonzero “fileoff” (file offset). Previously, the
fileoff was always 0. Previously, the fileoff for segments in the dyld
shared cache was the actual offset into the shared cache (not 0), but
special consideration was given to __TEXT segments which were forced to
0. See 10.12.4 dyld-433.5/interlinked-dylibs/OptimizerLinkedit.cpp
LinkeditOptimizer<>::updateLoadCommands(). Note the comment there where
the __TEXT segment’s apparent fileoff is set to 0:
// HACK until lldb fixed in: <rdar://problem/20357466>
// DynamicLoaderMacOSXDYLD fixes for Monarch dyld shared cache
Refer also to the lldb commit that references the above,
http://llvm.org/viewvc/llvm-project?view=revision&revision=233714.
Evidently, update_dyld_shared_cache has been revised to no longer apply
this hack in 10.13. Crashpad’s sanity check for __TEXT segments having a
fileoff of 0 is no longer valid, and causes it to reject modules loaded
from the dyld shared cache.
Since this was just a sanity check, remove it entirely.
This caused module information for modules loaded from the dyld shared
cache to be missing from minidumps produced on 10.13, which in turn
prevented symbolization in frames belonging to most system libraries.
For reasons not yet understood, I don’t see this problem in Chrome on
10.13db1 17A264c on a test virtual machine (HFS+ filesystem), although I
do see it on actual hardware (APFS filesystem), and I do see it in

10.13 introduces two new fields to dyld_all_image_infos. Oddly, it
doesn’t put them in the “reserved” area that was defined in this
structure. This addition made it necessary for the padding problem in
the 32-bit structure previously worked around in Crashpad to be
addressed in the native structure, so Crashpad’s definition is adapted
to match.
This fixes tests on 10.13 that verify that dyld_all_image_infos can be

Note that although the 10.13 SDK includes this structure extension,

_dyld_get_all_image_infos() was only used in test code in Crashpad.
This addresses two related problems.
When running on 10.13 or later, _dyld_get_all_image_infos() is not
available. It appears to still be implemented in dyld, but its symbol is
now private. This was always known to be an “internal” interface. When
it’s not available, fall back to obtaining the address of the process’
dyld_all_image_infos structure by calling task_info(…, TASK_DYLD_INFO,
…). Note that this is the same thing that the code being tested does,
although the tests are not rendered entirely pointless because the code
being tested consumes dyld_all_image_infos through its own
implementation of an out-of-process reader interface, while the
dyld_all_image_infos data obtained by _dyld_get_all_image_infos() is
handled strictly in-process by ordinary memory reads. This is covered by
bug 187.
When building with the 10.13 SDK, no _dyld_get_all_image_infos symbol is
available to link against. In this case, access the symbol strictly at
runtime via dlopen() if it may be available, or when expecting to only
run on 10.13 and later, don’t even bother looking for this symbol. This

Since Apple closed https://openradar.appspot.com/20239912 without fixing
anything, it looks like we’ll be stuck with these quriky cl_kernels
modules for quite some time. Allow these modules to be tolerated on any
OS version >= 10.10, where they first appeared in a broken state, by
removing the upper bound for the OS version to tolerate with this quirk.
The tolerance was previously expanded to include 10.11 in
cd1f8fa3d2f2c76802952beac71ad85f51bbf771 and 10.12 in
6fe7c5414e46acfa30e8984513bf0896e91b9407. After this third update, this
should hopefully no longer be an annual exercise.

I opted to leave casts to types that were definitely the same size
alone. reinterpret_cast<uintptr_t>(pointer) and
reinterpret_cast<intptr_t>(pointer) should always be safe, for example.
Casts to other integral types have been replaced with
FromPointerCast<>(), which does zero-extension or sign-extension based
on the target type.
To make it possible to use FromPointerCast<>() with some use sites that
were already using checked_cast<>(), FromPointerCast<>() now uses
check_cast<>() when converting to a narrower type.
Test: crashpad_util_test FromPointerCast*, others

When GetProcessInformation() obtains SystemProcessInformation, it
resizes its buffer as directed by NtQuerySystemInformation(). Nothing of
value resides in the old buffer if a resize is attempted, so it can be
freed before attempting to allocate a resized one.
This may help crashes like go/crash/f385e94c80000000, which experience
out-of-memory while attempting to allocate a resized buffer. It also may
not help, because the required buffer size may just be too large to fit
in memory. See https://crashpad.chromium.org/bug/143#c19.
